You will have to download the latest version of the DNG converter and convert your raw images to the DNG (Digital negative) format. Be sure to set the option to use Camera Raw 4.6 and later. If you are using a Mac the DNG converter only works on folders (at least that is my understanding). On the PC it is possible to convert individual images. Anyway, the DNG converter is a solution. The other solution is to upgrade to a newer version of Photoshop. Your choice.
